Video trying to use wrong codec

[[Neo770]]

Hi all,

I have these video's that were taken with our digital camera, still camera that is.

Now these files played fine last time I checked, but know I find that windows media player gives an unknown error when I try to play them.

Looking at the properties of the file I see windows thinks that the video format is DV which is wrong.

They still wont play if i remove the Panasonic DV codec I have installed.

Nothing else on the system will play them either.

My PC here is Server 2003, by dad's PC is XP and has the same problem.

Soooo, what the??

BTW: YAAI tool tells me the videos are M JPG

Get gspot, open the video file with it, see the right side about how many (if any) appropriate codecs are installed.
If none, install the codec gspot says it was encoded with.
If some, try and render the clip with the bottom-most section.

try uninstalling the camera software and drivers, reboot and reinstall. failing that, try installing something like ace codec pack or gordian knot codec pack. these both have a lot of video and some audio codecs in them. or the kazaa lite codec pack. some can be found at www.doom9.net

We dont have any camera software/drivers installed

And why should I have to go installing a codec pack when these files worked like last week.

Gspot says I have 2 compatable codecs installed MJPEG and AVI Draw. The render in GSpot was successful.

Heh, we had a customer who had the same problem... Couldn't play motion jpeg.

Every other computer was able to play it.

I have no idea if this will be of any help, but if you go to control panel->sounds and multimedia->hardware->video compressions->properties->preferences, you can possibly find the codec there. See if it's disabled. If not, you could try lowering/raising it's priority. If the proper codec has higher priority, it's my understanding that it will be used to render the stream.

//edit:
Sorry, they don't seem to have priority settings on video side, audio side has it.
Video side doesn't even seem to have enable/disable options.

//edit2:
It seemed when I was checking out the mjpeg file, that 'quartz.dll' was used to play it back. It's part of directx, so it might be your dx installation has become corrupt or something similar.

Ok thanks, both my dad and I installed Office 2003 and flash mx in the last few days so ill try reinstalling direct x, then if no go ill uninstall those apps and see what happens.

If anyone else has suggestions keep em comming, im going to bed soon so I wont be replying till tommorow.

OK on my dad's PC i reinstalled dx9b, that didnt help. Uninstalled Office 2003, that didnt help. Uninstalled Flash MX and that didnt help either.

So if anyone has anything id love to hear it. I'd hate to have to reinstall just for this.

That's pretty odd.

I just found another computer which refused to play the clip.
Installed dx9b_redist, and it plays fine.

Earlier though, gspot said that while codecs were installed, only partial rendering worked.

Yea the codecs are their, windows just wants to thinks its a DV file now. If I could somehow tell windows to use a different codec on the files then all should be good. But im not sure if that can be done?

You can play it with virtualdub, it has internal codec.
Just tested it with another computer.
